A partial tear of the left Achilles tendon has forced unbeaten lightweight contender Sharif "The Lion" Bogere out of his scheduled November 24 fight against Richard Abril for the vacant WBA Lightweight World Title at Citizens Business Bank Arena in Ontario, Calif.

Luckily, there was no evidence of a rupture in the 24-year-old Bogere's tendon and he is expected to be cleared to resume training in approximately four to six weeks. Talks are ongoing with respect to a date on which to reschedule this championship bout.

The HBO World Championship Boxing event, which is headlined by Robert "The Ghost" Guerrero vs. Andre Berto for the WBC Interim Welterweight World Championship, will proceed as scheduled with the junior middleweight clash between Keith Thurman and Carlos Quintana as the co-featured bout.
